“Downstream Error 408” in Tyk On-prem

Description

A user may receive the aforementioned error message in their logs whilst running an instance of Tyk.

Cause

This is caused by a NGINX or AWS ELB configuration somewhere on the upstream or downstream servers. Tyk is unable to perform retries after a 408 error, suggesting that the cause is external to Tyk itself.

Solution

The user should check their NGINX or ELB settings and amend where necessary.
